Answer:
(1+√7,0),(1−√7,0)
Step-by-step explanation:
You can't factor the expression evenly, so use the quadratic formula.
a = 2
b= -4
c= -12






End result: (1+√7,0),(1−√7,0)
Factor a square root of 14 out of every expression to get:



Thus, the expression is equal to four times the square-root of 14. The second answer is correct.

Answer:
The average distance from venus to mars is 2.5x10⁸ kilometers.
Step-by-step explanation:
We know:
d₁: average distance between venus and earth = 2.5x10⁷ km
d₂: average distance between mars and earth = 2.25x10⁸ km
We can find the average distance from venus to mars as follows:

First, we need to equal the base power 10 so we can sum both distances:
Now, average distance:
Therefore, the average distance from venus to mars is 2.5x10⁸ kilometers.
